Subject [jira] [Created] (DIRAPI-154) Implement "online" OpenLDAP schema parsing in DefaultSchemaLoader

Gerald Turner created DIRAPI-154:
------------------------------------

             Summary: Implement "online" OpenLDAP schema parsing in DefaultSchemaLoader
                 Key: DIRAPI-154
                 URL: https://issues.apache.org/jira/browse/DIRAPI-154
             Project: Directory Client API
          Issue Type: Improvement
    Affects Versions: 1.0.0-M20
            Reporter: Gerald Turner


The constructor in DefaultSchemaLoader has the following comment:
  // TODO Handle schema loading on other LDAP servers

For OpenLDAP this would require searching subtree under cn=schema,cn=config and handling attributes
like:

  olcAttributeTypes: {1}( 2.5.4.4 NAME ( 'sn' 'surname' ) DESC 'RFC2256: last (family) name(s)
for which the entity is known by' SUP name )

  olcObjectClasses: {4}( 2.5.6.6 NAME 'person' DESC 'RFC2256: a person' SUP top STRUCTURAL
MUST ( sn $ cn ) MAY ( userPassword $ telephoneNumber $ seeAlso $ description ) )

Note that there is also an 'olcObjectIdentifier' attribute type that seems to be used to create
macros for interpolation in OID's used in other attributes:

  olcObjectIdentifier: OLcfg 1.3.6.1.4.1.4203.1.12.2
  olcObjectIdentifier: OLcfgAt OLcfg:3
  olcObjectIdentifier: OLcfgOvAt OLcfgAt:3
  olcObjectIdentifier: OMsyn 1.3.6.1.4.1.1466.115.121.1
  olcObjectIdentifier: OMsBoolean OMsyn:7

  olcAttributeTypes: ( OLcfgOvAt:10.4 NAME 'olcUniqueStrict' DESC 'Enforce uniqueness of null
values' EQUALITY booleanMatch SYNTAX OMsBoolean SINGLE-VALUE )

However this additional complexity seems to only be used for the internal/vendor-specific
schema itself (not 'core', 'nis', etc.).

Attached is LDIF output of from searching cn=schema,cn=config.
